[Intel-gfx] [PATCH 0/2] Introduce Glamor to UXA framework.

[Zhigang Gong]

After discussion with Chris yesterday, I reworked the previous
glamor branch and concentrate the patchset to two patches. The 
first patch is the same as the previous. The second patch merges 
all the others into one, and made some slightly change. One major 
change is that I decide to extent the finish_access to handle the 
flushing operations by check the access type. And also add some
missed glamor flushing operations.

This patchset initially enable glamor with UXA. And two functions
,fill_spans and poly_fill_rects, go to the glamor path. I tested it
with render check, and it works fine.

One of the remaining issues is the vsync'ed copy. I discussed with
Chris, and already got a solution. Will do that when I enable
the copy_area to glamor path.
